TYPE-MACHINE MATRIX.

Specification of Letters Paten c.

Original application filed June 7, 1&99,

companying drawings, forming a part of this specification, and to the figures-and -lettors of reference marked thereon.

This invention relates to matrices for the cellular die cases of automatic type casting.

and composing machines, and is specially designed for use in connection with-the die case of application SeriallNo. 600.557jfiled June 7, 1905), of which this is a division.

2 The primary object of said invention is to provide a means for equipping the single unit cellular die-case with extended-face matrices occupying a plurality of cells, 'without in any degree. attecting the capacit-y of 2-5 said die case to zu'con-nnotlate single units, whereby extended face characters may be produced in conjunction with smaller point sizes within the capacity of the single unit matrices and associated mold.

In the accompanying drawings-Figure1 is a bottom plan View of the cellular die-case with the improved matrices applied thereto. Fig. 2 is a sectional view of the die case. Fig. 23 perspective view of im- 5 provemcnts as eml'aodied in a two-unit matriX, and Fig. a similar view of a fourunit matrix embodying the invention.

The san'ic numerals designate like parts in the several views.

40 The cellular die-case, sc-called, consists of a frame or plate- 1 with an opening therein divided into a series of rectangular cells of uniform dimensions and symmetrically disposed on two series of intersecting parallel lines. The cells are formed by a series of renmvalile parallel bars provided with lateral fingers One or more of said bars is furnished with a complement-ail series of tingers 4 opposite fingers 3 and a plain bar 5 is interposed between the proximate ends of fingers i and the ends of fingers.3 pertaining to the next adjacent bar 2. In the ordinary equipment each cell receives a single Patented Jan. 10, 1911.

matrix (3 of parallelepiped form and grooved peripherally as at 7 to approximately one-half the thickness of the walls of the cell,-t0 provide interlocking suspension shoulders and permit close approxnna. tion. of the sides of adjacent matrices; and each matrix is furnished with'a mold-engaging surface and contained. matrix cavity 9 at the opposite end.

' It is sometimes required, as for example when setting up advertising matter, to as soci'ate letters or characters of larger'size with those re resented in regular die-case equipment an mold, the latter variable, set,- wise, but having'a fixed point dimension.

To,

mum capacity withininimum weight the I To enable such extended characters to be die-case with one or more matrices .of :1 nortion of single unit matrices Supplemental fingers 4 on one of the bars 2 and the plain bar 5 have been introduced in the construe-- and, in addition thereto the matrix is slotted, as at 11, for the passage of plain barb, and in the caseof a four-unit matrix, Fig.

4, it is also slotted at 12 for the reception of the intermediate fingers 3 or 4 or both. Each matrix is thus provided with a plurality of retaining, z. 6., supporting and squaring sections 15, one foreach cell oc'cupied,--a fea ture of considerable importance for preventing displacement, more especially where the centering cavity is disposed eccentrically of. the axis of the matrix as will presently appear. i

The centering cavity 13 is located eccentrically of the matrix in alinement with that one of the occupied cells registering with the die-case adjusting mechanism, and the matrix cavity, l4.is justified with relation to one of the sides nearest the .centering cavity, to the end that the line side of the extended type may coincide wit-h that ofthe single unit matrices associated therewith.-

In practice thematrices and suspension bars 2 and 4 for the equipment of any given die-case are assembled according toaprearranged plan of distribution, the multiple unit or extended facematrix or matrices occupying cells on opposite sides of plain bar 5 groove while the one-unit matrices. are distributed among the remaining cells. In a com lete equipment all the cel s areoccupied bye aracter, quad or space matrices,but as is obvious a less number may be employed, as 'indi cated in Fig.1, wherein only a few of the cells are shown thus ooc'upie By locating the centering cavity 13-eccentrically of the multiple cell matrices and in register 'with'the cellular unit of the die-- case the same adjusting mechamsms can be.

either in the positioning devices or the diecase.

-what we claim as new, and desire 'to secure by Letters Patent of the United States, is

1. A type matrix for the cellular die-case of automatic. type casting machines provided with a matrix cavity in one end and an eccentrically disposed .centering cavity in the opposite end.

2. A type matrix of arallelepiped form grooved peripherally, s otted transversely, and provided atone end with a matrix cavity andat the opposite end with an eccentrically disposed centering cavity.

.3. A type matrix for cellular die-cases the bod whereof is slotted transversely and peripherally to form suspension shoulders and a plurality of retai-mn sections adapted to occupy adjacent cells in the die=case and be engaged by the surrounding ,walls thereof. a
